It was a casting coup of the year when Yash Raj Films convinced Hrithik Roshan and Aishwarya Rai to be part of their Dhoom 2 but as the latest reports are pouring in, it seems pretty unlikely that Ash will be able to team up with Roshan.

According to some, it is Aishwarya's reluctance to play a negative role which is stopping her from doing suchinteresting project.

"The pretty lady is not over her Khakee experience," says an insider.

On the other hand Hrithik is quite excited about his new role. But would Ash join him on the fast bike, only time will tell.
